One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant species due to their loss of habitat. When forests are wiped out, the land becomes exposed, leaving it vulnerable to being washed or blown away by elements. The scientific consensus on deforestation is that it intensifies climate change at a dramatic rate. Since different species eat different foods and live in different types of habitats, a diverse set of vegetation can enable a greater variety of animals to live in an area.

The South American rainforest, for example, influences regional and perhaps even global water cycles, and it's key to the water supply in Brazilian cities and neighboring countries. Deforestation weakens this process, leading to irregular rainfall patterns including drought and flooding. Ecohealth Alliance researchers have proposed that containing diseases could be considered a new ecosystem service, that is, a benefit that humans freely gain from natural ecosystems, just like carbon storage and pollination. Earths croplands, which cover about 49 million square km (18.9 million square miles), are mostly deforested land. Florida, United States Deforestation Rates & Statistics | GFW Even when the forest is not entirely cleared, what remains is often a patchwork of forests and fields or, in the event of more intensive deforestation, islands of forest surrounded by a sea of deforested areas.

Wood Products Deforestations effects reach far beyond the people and animals where trees are cut. Deforestation Effects Everglades in crisis: can this Florida treasure avert an As those gases enter the atmosphere, global warming increases, a trend scientists now prefer to call climate change. A major contributor to tropical deforestation is the practice of slash-and-burn agriculture, or swidden agriculture (see also shifting agriculture). However, the rapid destruction of forests is contributing to a decline in biodiversity never seen before. Deforestation is a major cause of soil erosion, perhaps the main cause. Deforestation also affects nearby rivers, streams, and other water sources as nutrients from the soil are removed through leaching, which happens when water (e.g., from rain) removes soluble nutrients from the soil and carries them elsewhere. DeSantis isnt exactly a global warming warrior he prefers Teddy Roosevelt conservationist but he will at least utter the words climate change, unlike Scott, who reportedly banned the term.
