Farmers use insecticides and fertilizers on their fruit and vegetable crops. which best describes the effect of these chemicals?

1 answer:

4 0

Pesticides and fertilizers can harm public health and the environment. Many of pesticides contain toxic chemicals that can cause negative health effects such as neurological and cancer and reproductive disorders. Also pesticides can migrate into lakes and streams as they are swept away when it rains. On the other hand fertilizers do cause ground water contamination e.g Nitrogen fertilizers break down into nitrates and travel easily through the soil because of their solubility. this makes them stay in ground water for decades the addition of more nitrogen over the years has accumulative effect.

The illustration shows one of the ways resources are removed from the deep sea. There are many confusing regulations that limit

Sonbull [250]

The United Nations Conventions on the Law of the Sea (UNCLOS) stipulates that seabed area, which is not within the landmark of any particular country should be regarded as a common natural heritage. Consequently, any mineral found in such an area can be used by anyone.

However, because of the abundant presence of sea area, and the way national boundaries often conflict, coupled with the problem of illegal mining practices, such laws are difficult to enforce, and so these regulations are not standardized yet.

Some possible impacts of ilegal seabed mining are:
1. Destabilisation of oceanic systems.
2. It constitutes danger to the organisms living in the hydrothermal vents.

Which of the following have been linked to the dramatic global decline of amphibian populations? Select one: a. drainage of wetl

charle [14.2K]

<h2>The correct answer is: e.</h2>

Explanation:

Decline in the global population of amphibians is due to multiple reasons which include:

A moist ecosystem is necessary for amphibians especially for the purpose of their reproduction. The drainage of the wetlands deprives them of their habitat.
Pollutants adversely affects the survival of the gametes, tadpoles or the adult amphibians by acting as toxic agents and inhibiting their normal metabolic function.
Infectious diseases often cause their death resulting their population to decline.
Global climate warming affects their normal metabolic growth and development and hence causes their population to decline.
