What does agriculture do to the ocean?

Essentially, the once-fresh inputs of clean, natural water into the ocean are being replaced by flows of polluted farm runoff. And on a massive scale. It’s no wonder that animal agriculture is the leading cause of species extinction, ocean dead zones, water pollution and habitat destruction, according to the EPA.


What are threats to the coast?

The threats to coastal communities include extreme natural events such as hurricanes, coastal storms, tsunamis, and landslides, as well as longer-term risks of coastal erosion and sea level rise. Floods are the most frequent natural disaster; one in three Federal disaster declarations is related to flooding.

How does pollution affect the estuarine ecosystem?

Coastal and estuarine ecosystems have been, and still are, heavily influenced by humans through pollution and habitat loss worldwide. Over 80% of all marine pollution originates from land-based sources which are primarily industrial, agricultural and urban . Pollution accompanies most kinds of human activities, including offshore oil and gas production and marine oil transportation. Besides altering the marine environment, pollution also causes economic losses .


What happens to contaminants after entering the sea?

After entering the sea, contaminants are usually diluted and widely dispersed. However, the adsorption of contaminants to suspended solid material in the sea leads to the occurrence of elevated concentrations in the seabed in areas where this material settles.


How can anthropogenic chemicals affect wildlife?

It is now well established that there are anthropogenic chemicals released to the environment that can disrupt the endocrine systems of a wide range of wildlife species. The reproductive hormone-receptor systems appear to be especially vulnerable. Indeed, changes in sperm counts, genital tract malformations, infertility, an increased frequency of mammary, prostate and testicular tumours, feminisation of male individuals of diverse vertebrate species and altered reproductive behaviours, have all been reported . With regard to environmental management, the problem of endocrine disrupting chemicals is extremely difficult to address. Basic research is required to strengthen the scientific foundation for risk assessment: e.g., baseline studies on endocrine dysfunction across classes of animals to reduce the uncertainty associated with species extrapolations . See also articles under the Ecotox Portal.


What are PCBs found in?

It is unclear how organic synthetic organic chemicals affect marine organisms but PCBs, for instance, are frequently found in fish liver, seal blubber, bird eggs, and human fat. Organochlorines have been associated with impaired reproductive ability in seals and whales.

Why is irrigation important?

Irrigation, the process of applying controlled amounts of water to plants, can also create various problems for the environment. It can lead to the depletion of underground layers of water that are crucial for the environment.


What happens when algae sinks?

When the algae sink and decompose, the process depletes the oxygen in the water. As increases in spring runoff bring more nitrogen, phosphorus, and other pollutants into coastal waters, many aquatic species could be threatened. [1] Decreases in precipitation could also increase the salinity of coastal waters.


What are dead zones in the Gulf of Mexico?

Some coastal areas, such as the Gulf of Mexico and Chesapeake Bay, are already experiencing “dead zones.”. Dead zones occur when land-based sources of pollution (e.g., agricultural fertilizers) contribute to algal blooms. When the algae sink and decompose, the process depletes the oxygen in the water.


What areas of New York were flooded by the storm surge?

For example, low-lying areas of New York City, Long Island, and New Jersey were flooded by several feet of water by the storm surge from Superstorm Sandy in 2012. [2][5] Sea level rise could magnify the impacts of storms by raising the base on which storm surges build. [7]


How does acidic water affect corals?

A more acidic ocean adversely affects the health of many marine species, including plankton, mollusks, and other shellfish. In particular, corals can be very sensitive to rising acidity, as it is difficult for them to create and maintain the skeletal structures needed for their support and protection.


What are the impacts of storm surge?

Storm surges flood low-lying areas, damage property, disrupt transportation systems, destroy habitat, and threaten human health and safety.


How many square miles of wetlands have been lost in Louisiana?

For example, coastal Louisiana lost approximately 2000 square miles of wetlands in recent decades due to human alterations of the Mississippi River’s sediment system and oil and water extraction that has caused land to sink.


What is relative sea level?

The terms “local” or “relative” sea level refer to both the global change in sea level and the effects of land motion. Where the land is sinking, the rate of relative sea level rise is larger than the global rate. Some of the fastest rates of relative sea level rise in the United States are occurring in areas where the land is sinking, …


What are the effects of land use changes on agriculture?

In almost every case, land use changes — say, deforestation, or paving over green space for suburban expansion — result in more surface warming.


How much carbon dioxide does organic farming remove from the air?

We’ve said it before and we’ll say it again: Organic agriculture can remove from the air and sequester 7,000 pounds of carbon dioxide per acre per year. The Rodale Institute study that found that staggering number also found that, when properly executed, organic agriculture does not compromise yield.


Does drought increase yield?

As a matter of fact, in drought years, it increases yield, since the additional carbon stored in soil helps it to hold more water. In wet years, the additional organic matter in the soil wicks water away from plant roots, limiting erosion and keeping plants in place.
