The Problems of Earth resume: Loss of biodiversity

Image
Loss of biodiversity is a decrease in the diversity of life forms within a species, an ecosystem, or the Earth as a whole.   Brazilian Amazon rainforest (International Business Times, 2018) The loss of biodiversity can lead to a breakdown in the functioning of the ecosystem where decline has happened. An area’s biodiversity may increase and decrease following natural cycles. In contrast, human-driven biodiversity loss tend to be more severe and longer-lasting: ecosystems have adapted to the challenges of natural disturbances. However, humans, our crops, and our food livestock take up half of the world’s habitable land, and overexploits 90% of the fishing stocks. This massive conversion of forests, wetlands, grasslands, other terrestrial ecosystems, and the ocean, has produced a 60% decline in the number of vertebrates worldwide since 1970.  The Rockefeller Foundation/Lancet Commission reports that human health depends on natural systems functioning properly.

The Problems of Earth: The role of agriculture in the soil quality

Image
By "the role of agriculture in the soil quality" we refer to the  effect that the science, and art of cultivating plants and livestock significantly has on the ability of the soil to perform its essential  functions.  Cropland spraying ( irxp.com , 2018) Soil is an important natural resource supporting plant, animal, and human populations and is a habitat for a diversity of species. Productive soils throughout the world are being degraded rapidly due to human activities. Declining soil quality over the past century has manifested itself in loss of agriculturally productive lands, forests, and wetlands due to overuse.  The quality of the soil is essential because it is the beginning of the quality of the food. That quality of food provides health quality . Therefore, if we grow croplands on poor soil, we will be feeding ourselves with poor food and we will have a poor health. Our health and the health of our planet are connected. In every handfu...
