Sumatran rainforests, which are home to most of the world’s orangutans, are being ravaged for palm oil and paper products. Rhinos, tigers, and gorillas are being displaced by deforestation and illegally poached in Asia and Africa.

How does deforestation affect soil?

Deforestation removes vegetation, which anchors soil in place. Without enough trees, soil is vulnerable to erosion and nutrient loss. The absence of roots causes topsoil to easily wash or blow away, leading to decreased soil quality and increased landslides. It’s estimated that a third of the world’s arable land has been lost to soil erosion and degradation since 1960. Once land is cleared and roots are ripped away, cash crops like coffee and soy are planted which can make erosion worse, since their roots cannot anchor into the soil like those of a tree.

What are the causes of crop extinction?

Deforestation is a leading cause of climate change, which is a leading cause of crop extinction. If our forests continue to vanish and release greenhouse gases into the air, crops like coffee, tea, avocados, chocolate, and bananas could be largely lost in our lifetime.

Why is farmland being lost?

And, of course, some of the farmland being lost is for so-called “specialty” crops, like fruits and vegetables. But there are other reasons as well. Development on farmland can have negative effects, removing land that animals use as a habitat. Well-operated farms care for the soil, air, and water, and produce viable ecosystems.

Why is farmland less important than food?

This is concerning for a variety of reasons. The obvious one is that farmland produces food, so less farmland means the price of food may rise . The majority of American farmland is devoted to commodity crops – soy, corn, wheat – and many of the uses of those crops are not for direct eating.

When was agricultural land converted to urban land?

This image, courtesy of American Farmland Trust, shows the conversion of agricultural land to urban and low-density residential development between 1992 and 2012.

How does land clearance affect the ecosystem?

Land clearance greatly impacts on the health of rivers and coastal ecosystems. It increases erosion and the runoff of sediment, nutrients and other pollutants into coastal waters, causing damage to coral reefs and other marine ecosystems such as se agrass beds . Increased nutrients in rivers and streams can cause outbreaks of toxic algae.

How does land clearing affect animals?

Land clearing kills animals directly. Millions dies each year during land clearing operations. Ten million are being lost each year in NSW alone. This occurs when they’re harmed during land clearance operations, lose their shelter and are exposed to the elements and feral predators, and because they lose their food sources.

How are native birds declining?

Native birds are declining precipitously . [ 3] Populations of Australian terrestrial birds have declined by 50% since 1990. [ 4] Even once-common birds are now in trouble in many areas. [ 5] Many threats are responsible, but habitat loss through land clearance and subsequent decline in the condition of isolated remnant habitat is high among them.

How does clearing a habitat affect the environment?

Clearing removes habitats, leading to the direct loss of millions of native animals and plants every year. Australia’s mammal species have suffered an extraordinary rate of extinction over the last 200 years. [ 2]

How do forests help the environment?

They serve as carbon sinks, absorbing carbon released into the atmosphere from fossil fuels. Conversely, when forests are cut down, they release that carbon back into the air. Twenty percent of global greenhouse gas emissions come from felling the world’s forests.

How much land does livestock take up?

Livestock takes up nearly 80% of global agricultural land, yet produces less than 20% of the world’s supply of calories (as shown in the visualization). This means that what we eat is more important than how much we eat in determining the amount of land required to produce our food.

What is the dominant contributor to dietary land requirements?

The second consideration to note is that, as we have explored above, the dominant contributor to dietary land requirements is livestock rather than crops. Although productivity in livestock farming has increased over the last 50 years, this change has been more modest than gains in crops yields; the meat yield per cattle has increased by approximately one-third since 1961, which is significantly lower than improvements in cereal yields, which have grown more than five-fold across many countries. This increase in animal productivity has also been strongly offset by global meat production which has more than quadrupled over the same period.

How can we make the highest impact change to our diets?

How do we do this? Arguably the highest-impact change we can make to our diets is to reduce our meat intake—particularly that of beef or mutton. In the chart below we see the relative land requirements per gram of protein across a range of food commodities. 4

What is the relationship between beef consumption and land use?

Here we see a very strong relationship: the more beef we eat, the higher our land use requirement. Such strong correlations are not seen for other meat types, such as pig meat (where there is no clear relationship between intake and land requirements). The key outlier on this plot is New Zealand—its population also has a strong preference for lamb/mutton, which requires a similar amount of land per kilogram of meat as beef does.

Does food affect land use?

Alexander et al. (2016) highlight that the types of foods we eat have a much stronger impact on land use than the quantity alone. The land requirements of different diets tend to be most strongly correlated to a country’s level of per capita meat consumption—and most notably that of ruminants (beef and mutton). 2,3

Is there a difference in land requirements between countries?

Nonetheless, there are still large differences in dietary land requirements between countries of a similar income-level. Why, for example, is the requirement for a New Zealander more than double that of a UK citizen, despite them having similar levels of prosperity?

Why is there a trade-off between environmental impact and nutrition?

The implication is that there is an important trade-off between environmental impact and nutrition: for a variety of ecological reasons, including biodiversity and climatic change, we want to reduce our agricultural land pressures; but we also want a healthy and adequately nourished population.

What percentage of land clearing is done in Queensland?

A 2017 government report states that 93% of the land clearing (deforestation) in Queensland (the large north-eastern state of Australia) is being done to make pasture for livestock; for eventual human consumption.

Regards land clearing and reduced rainfall, from a 2016 report: “ Stopping land clearing and replanting trees could help keep Australia cool in a warmer future … Land clearing releases greenhouse gases into the atmosphere, but the effect of land clearing on climate goes well beyond carbon emissions. It causes warming locally, regionally and even globally, and it changes rainfall by altering the circulation of heat and moisture …

What is happening in the oceans, seas and rivers?

Excerpts from articles about the marine ecosystem collapse that is happening now in oceans, seas & rivers due to over-fishing and the toxic pollution in waterways from land-based animal agriculture meat-farming; worsening climate change; threatening the entire food chain.

Where are the oldest trees being cut down?

some of Australia’s most majestic and oldest trees are being cut down for timber by a state-owned company in Victoria, which has even less left to lose than NSW. And Tasmania has just signed up to allow more logging in its national parks…”. …

What is the main cause of clearing?

The main cause of clearing is for pasture… . ” [1] A definition of pasture is “land covered with grass and other low plants suitable for grazing animals, especially cattle or sheep.”. [2] In other words the main cause of deforestation in Australia was to benefit the profits of the animal agriculture livestock industries.

Is destruction of nature dangerous?
