Trees act as a carbon sink: that is, they absorb carbon dioxide, an unwanted greenhouse gas, out of the atmosphere. Removing trees releases carbon dioxide into the atmosphere and leaves behind fewer trees to absorb the increasing amount of carbon dioxide in the air. In this way, deforestation exacerbates climate change.
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 .
The World Counts shows that there is 15 years until Earth is exhausted of freshwater, and 23 years until there are no more fish in the oceans. They also estimate that 15 billion trees are cut down every year, while only 2 billion trees are planted every year, and that there is only 75 years until rainforests are completely gone. [72] [73]
More than half of all plant and land animal species in the world live in tropical forests. [21] As a result of deforestation, only 6.2 million square kilometres (2.4 million square miles) remain of the original 16 million square kilometres (6 million square miles) of tropical rainforest that formerly covered the Earth.

To insulate the roots of your plants, add a 2—to 3-inch layer over the soil. Compost Wood chips are carbon-rich, making them a great material to use in compost.
Warmer conditions would favour growth of certain bacteria species, shifting the bacterial community composition. Elevated carbon dioxide would increase the growth rates of plants and soil microbes, slowing the soil carbon cycle and favouring oligotrophs, which are slower-growing and more resource efficient than copiotrophs.

It shelters the soil from winds, which results in decreased wind erosion, as well as advantageous changes in microclimate. The roots of the plants bind the soil together, and interweave with other roots, forming a more solid mass that is less susceptible to both water and wind erosion. The removal of vegetation increases the rate of surface ...
If the soil is less fertile or sandy, provide a slow-release general fertilizer when the plants begin to bloom in spring. Pruning. Snowdrops don’t need to be pruned or deadheaded. The leaves ...
