write five harmful effects of deforestation
Answers
Harmful effects of deforestation :
1)Deforestation increases the level of carbon dioxide in the atmosphere. This causes the greenhouse effect which leads to global warming.
2) Deforestation increases temperature, reduces rainfall and increases wind velocity. These changes lead to climatic changes.
3) Disturbed water cycle, reduced rains and lowering of water table due to the removal of trees causes frequent droughts.
4) Deforestation leads to loss of natural habitats of wildlife and depletion of their food sources. This condition leads to loss of wildlife.

1 – The Effects of Deforestation on Biodiversity
definition what is deforestation impacts solutions.jpg
The most known consequence of deforestation is its threat to biodiversity. In fact, forests represent some of the most veritable hubs of biodiversity. From mammals to birds, insects, amphibians or plants, the forest is home to many rare and fragile species.
80% of the Earth’s land animals and plants live in forests.
By destroying the forests, human activities are putting entire ecosystems in danger, creating natural imbalances, and putting Life at threat. The natural world is complex, interconnected, and made of thousands of inter-dependencies and among other functions, trees provide shade and colder temperatures for animals and smaller trees or vegetation which may not survive with the heat of direct sunlight. Besides, trees also feeding animals with their fruits while providing them with food and shelter they need to survive.
Aren’t you yet sure about the importance of biodiversity for the planet’s balance and for human life? Then you should find out some examples of how Life is interconnected:
2 – The Effects of Deforestation on Local People and Their Livelihoods
Healthy forests support the livelihoods of 1.6 billion people globally, one billion of whom are among the world’s poorest. This means there are many people depending on forests for survival and using them to hunt and gather raw products for their small-scale agriculture processes. But in developing countries such as Borneo, Indonesia, Vietnam, Brazil, or Mexico, land tenure systems are weak. This allows big businesses to get these lands and use them for other ends, disrupting local people’s lives.
Locals then have to make one of two choices. They can decide to abandon “their” land and migrate somewhere else, avoiding conflict and embracing the challenge of a new different life. Or they can stay and work for the companies exploring it in remote plantations – often getting unfair wages and working under inhumane conditions. In some countries like Mexico, plantations’ owners are often forced to share their profits with local cartels to keep their families alive and to avoid having their crops burned

3 – Deforestation for Food May Lead to Food Insecurity in the Future
Today, 52% of all the land used for food production is moderately or severely impacted by soil erosion. In the long term, the lack of healthy, nutritious soil can lead to low yields and food insecurity.
4 – Soil Erosion is One of the Consequences of Deforestation
Deforestation weakens and degrades the soil. Forested soils are usually not only richer on organic matter, but also more resistant to erosion, bad weather, and extreme weather events. This happens mainly because roots help fix trees in the ground and the sun-blocking tree cover helps the soil to slowly dry out. As a result, deforestation will probably mean the soil will become increasingly fragile, leaving the area more vulnerable to natural disasters such as landslides and floods.
5 – Deforestation Affects and Contributes to Climate Change
Deforestation also has a very strong contribution to climate change. Why? Let’s remember trees absorb and store CO2 throughout their lives. If we speak about tropical forests, they hold more than 210 gigatons of carbon, according to WWF. And what’s worrying is that the destruction of these trees has two big negative side-effects.
