The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the ...
No rainforest today can be considered to be undisturbed. [33] Human-induced deforestation plays a significant role in causing rainforests to release carbon dioxide, [34] [35] [36] as do other factors, whether human-induced or natural, which result in tree death, such as burning and drought. [37]
Experts do not agree on whether industrial logging is an important contributor to global deforestation. [110] [111] Some argue that poor people are more likely to clear forest because they have no alternatives, others that the poor lack the ability to pay for the materials and labour needed to clear forest.

From climate change to species loss and pollution, humans have etched their impact on the Earth with such strength and permanence since the middle of the 20th century that a special team of ...
Deforestation in the Maranhão state, Brazil, in July 2016. The Amazon rainforest, spanning an area of 3,000,000 km 2 (1,200,000 sq mi), is the world's largest rainforest.It encompasses the largest and most biodiverse tropical rainforest on the planet, representing over half of all rainforests.
Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [ 4 ] [ 5 ] Greenhouse gases are emitted from deforestation during the burning of forest biomass and decomposition of remaining plant material and soil carbon .
Probably the most profound impact that habitat destruction has on people is the loss of many valuable ecosystem services. Habitat destruction has altered nitrogen, phosphorus, sulfur, and carbon cycles , which has increased the frequency and severity of acid rain , algal blooms , and fish kills in rivers and oceans and contributed tremendously ...
Addressing the impacts of climate change on tropical regions requires global cooperation and local action. Strategies include protecting and restoring ecosystems, implementing sustainable land use and fisheries management practices, and reducing greenhouse gas emissions. Technological innovations, such as satellite monitoring of deforestation ...
