The environmental impact of agriculture involves a variety of factors from the soil, to water, the air, animal and soil diversity, plants, and the food itself. Some of the environmental issues that are related to agriculture are climate change, deforestation, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
A study highlighted in a 2022 Nature article underscores the broader climate benefits of tropical forests beyond carbon storage. Tropical forests cool the planet by one-third of a degree through biophysical mechanisms such as humidifying the air and releasing cooling chemicals, in addition to their role in extracting carbon dioxide from the air.
The typical tropical forest may become a carbon source by the 2060s. [46] Researchers have found that, in terms of environmental services, it is better to avoid deforestation than to allow for deforestation to subsequently reforest, as the latter leads to irreversible effects in terms of biodiversity loss and soil degradation.

The only way to meet both goals is to find more paths for people to make a living in the Amazon without further destroying the rainforest, say experts who have long worked in the region.
As environmental activists raised the alarm about the palm oil industry's toll on the tropical forests of Southeast Asia two decades ago, Unilever, the world's largest buyer of palm oil, teamed up ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
In another article published by Nature, it points out that tropical deforestation can lead to large reductions in observed precipitation. [15] This concept of land-atmosphere feedback is common among permaculturists, such as Masanobu Fukuoka, who, in his book, The One Straw Revolution, said "rain comes from the ground, not the sky." [16] [17]
The Amazon rainforest in Brazil is facing a severe drought that may affect around 500,000 people by the end of the year, authorities said Tuesday. Amazonas state declared an environmental ...
