palm oil companies are responsible for the deforestation. No other ecosystems were effected but if Borneo continues at its current rate of deforestation it will increase risk of floods and forest fires. Logging, mining, and plantation development, especially from palm oil plantations have contributed to massive…

By: Emily St. Aubin The problem I am talking about is pesticides used in farming leaching leaching into the ground and ending up un rivers, lakes, and oceans contaminating wells and our drinking supplies. Pesticides include herbicides, fungicides, insecticides, fumigants, bactericides, rodenticides, baits, lures, and repellents.…

There are many things that are causing this. That is what we will be mainly talking about. The bees do so much for us and we barely do anything in return.

Bees and most pollinators are declining largely in numerous parts of the world due to intensive farming practices, mono-cropping, excessive use of agricultural chemicals, humid temperatures caused by climate change, nutrition lack, deforestation, pollution etc. In recent years declining bee populations have led to decreased floral reproduction, lower fruit yields, and less biodiversity causing rapid impacts…

Intensive Water Usage

Intensive farming has widespread negative consequences on the marine ecosystem and water supply. Running off from barnyards and feed lots can carry manure into our water system. Excessive use of fertilizers also contaminates water bodies, rivers and lakes (Pollution). All biotic ecosystems are affected in these operations because pollution from run…

Intensive Water used by Farming/Agriculture

Will Schweyer  The main ecological issue is overfishing. Aquatic ecosystems are affected by overfishing because if there are losses in fish then other ocean creatures will slowly die of. Japan, China, the U.S., Indonesia, Chinese Taipei, and South Korea are the main issue of overfishing, and the long-term effect of overfishing is loss of fish, which would mean loss of other ocean animals such as, such as, killer whales, sharks, sea lions, and any other ocean carnivore. Coral reefs…
