I have witnessed this in Africa on a micro-level. I have seen land cleared for agriculture with an immediate drying up of once permanent streams, thus illuminating the only water sources for miles. I have witnessed the shortening of the raining season along with the extension and increased severity of the dry season in West Africa. I have seen the desert expand southward as the savanna turns into desert. The longer term consequences will affect us all globally.

People now: Hey, we have plenty of trees!
People in 3000: I BUY OXYGEN EVERYDAY!

Madagascar is bleeding red. The landslides and mudflows from deforestation are really sad. 😢

When trees are felled, they do NOT release their carbon into the atmosphere. They do so, if they are burnt, or if they rot. Using timber for long term building material, to name one example, does in fact store the carbon, as long as the wood stays in its form. There are obviously still many reasons why deforestation and industrial scale timber harvestment have some big Issues, but i just wanted to correct this a little.

My response after seeing this video is that I am concerned about the deforestation, because forests play an important role in supporting life on earth. Forests are a source of oxygen that we breathe to survive. There will be many problems that arise if we continue to use the existing forest without replanting it. These problems are like the glass effect that arises from human activities that produce CO2 gas. If deforestation continues, no one absorbs CO2 further, the effect of these greenhouse gases cancels global fires which have an impact on glaciers, drought, forests, causing habitat for these animals to become extinct and causing the ecosystem on earth to become unbalanced.

This is so relevant. We must protect our environment if we want to live longer!

Hutan sangat berperan penting bagi kehidupan makhluk hidup. Seperti yang telah dikatakan dalam video tersebut, bahwa hutan adalah habitat atau tempat tinggal bagi 80% tumbuhan dan hewan . Penggundulan hutan dapat menimbulkan efek yang sangat luar biasa. Efek yang akibatkan penggundulan hutan yaitu emisi gas rumah kaca yang menyebabkan efek rumah kaca. Seperti yang kita ketahui, efek rumah kaca berkaitan erat dengan pemanasan global. Oleh karena itu, pemanasan global akan semakin bertambah tiap tahunnya. Selain itu, efek sampingnyalagi adalah kepunahan. Sekitar 4 sampai 6 ribu spesies telah punah akibat penggundulan hutan. Sehingga keanekaragaman hayati dalam hutan tidaklah seimbang.

Forests are very important for the life of living things. As has been said in the video, that the forest is a place to live for 80% of plants and animals. Deforestation can have biggest effects. The effect from deforestation is the emission of greenhouse gases which causes the greenhouse effect. As we know, the greenhouse effect is closely related to global warming. Therefore, global warming will increase every year. Besides, another side effect is extinction. About 4 to 6 thousand species have become extinct due to deforestation. So that the biodiversity in the forest is not balanced.

Mother of 2020: dinosaurs used to be very big. But they're all extinct.
Kid: were they bad?
Mother: they'd kill you alive.
Kid: Thankyou God!

Mother of 2050: trees used to be very big. But they're all extinct now.
Kid: were they bad?
Mother (changes topic): Lets hurry the oxygen cylinder might run out of stock!!

What this video mentions only briefly is how not all forestry and logging activities lead to deforestation. Deforestation occurs when the land is converted from forest land into another landuse. This is primarily happening in second and third world where they lack other opportunities for national income such as manufacturing, tech, etc. So land is cleared and converted into other uses such as cattle or plantations. Modern forestry in developed countries is based on 100+ years of science and experience to ensure that we will have forests in perpetuity. There are third party certifications that allow you to see that the wood based products you are purchasing are sourced sustainably. Sustainable Forestry Initiative (SFI) and Forest Stewardship Council (FSC) are two of the prominent ones. So next time you see a clearcut, don't just assume that it will never grow trees again, it is more then likely that it will be replanted to grow trees for the next generation.
