how plantation farming, overfishing, and the international lumber trade each hurt the environment. Discuss each one separately.

Plantation farming and lumber trade are directly destroying the forests, while overfishing is disturbing the marine ecosystems.

Explanation:

Plantation farming is farming on a very large scale. We can take the palm plantations which are used for getting palm oil. Indonesia is the largest producer of it, but in order to make the enormous palm plantations, which are still growing in size, it cleared out and destroyed huge areas of tropical rainforests, thus destroying the ecosystem in full.

The lumber trade is a trade with wood that is used for numerous reasons and products. In order to get enough wood to satisfy the demand on the global market, the companies cut down the trees of enormous areas. While they can make it sustainable by simply planting saplings in the places where the older trees were cut, this is rarely done, so the forests and ecosystems are rapidly destroyed and not renewed.

One of the most popular in the cuisines around the world is the fish. With the global population rising and the standard of living rising as well, more and more people use more and more fish. The fishing companies are barely managing to satisfy the demand on the market even though they are overfishing heavily. The overfishing has led to the extinction of a lot of species and putting numerous others on the verge of extinction, and this is creating total chaos in the marine ecosystem and has huge consequences for the other organisms.

b - north american plate;

huge continental plate, occupying big portion of the northern hemisphere.

c -eurasian plate;

alongside the north american plate, it is one of the two dominant continental plates in the northern hemisphere.

d - indian plate;

a small continental plate, that has been part of gondwanaland initially, but after the break up of it, moved towards northeast and pushed into the eurasian plate that was once part of laurasia.
