Climate changes changing ecosystems

English

In this article “Climate change may bring big ecosystem changes” written by NASA, the issue of global warming and the ways it affects ecosystems is dealt with. Climate change is a big issue globally, it affects the overall temperature of the world, but it also affects ecosystems. This article outlines that different plant and animal species in certain ecosystems are adapted to a certain climate, when these climates change the species need to migrate to places where the climate is adequate for their survival.

Climate change may bring big ecosystem changes

English

This present study’s aim conducted by researchers of NASA’s jet propulsion laboratory and the California Institute of technology of Pasadena was to calculate the Earth’s ecological sensitivity towards climate changes. The study predicted that by 2100, climate changes will modify almost half of the plants communities covering the planet. As a result of rising human-produced greenhouse gases, the Earth’s climate is changing tremendously.

Water Bodies at high risk

English

In his article presented in The Guardian, author Oliver Milman exposes the problem of the food chains of the ocean being at high risk. With studies, researchers establish that the climate change affects the marine diversity. Because the ocean absorbs carbon dioxide and the burning of fossil fuels has increase, this caused the water bodies to warm up and to become more acid. Other consequences such as putting some species in danger, increase the sea level, endangering the coral reef are all caused by greenhouses gases, overfishing and pollution.

“Ecosystems Could Once Bounce Back From Wildfires. Now, They’re Being Wiped Out for Good”

English

In the article “Ecosystems Could Once Bounce Back From Wildfires. Now, They’re being wiped out for good” written by Lakshmi Supriya, the author informs the readers about ecosystems losing their resiliency, meaning they can’t bounce back from disturbances, more precisely, he explains how an ecosystem can be completely ravaged by uncontrollable forest fires without the ability to grow back. He explains that forest fires are a natural and essential way to allow reproduction and new nutrients to grow, therefore new beginnings for the plants and trees.

How Human Activities Affect the Ecosystem

English

The article “Human Activities that Affect the Ecosystem” by David Weedmark has for purpose to inform us how human activities affect the ecosystem being the water, the air, the land and the life that we share the world with. According to the article, there are few causes that explain how human activities is destroying the ecosystem. The first one that Weedmark mentions is pollutions. He claims that humans are dumping more than 8 million tons of that plastic into the oceans. In consequences,  wildlife in the sea is deeply affected.

Consequences on ecosystems

English

The purpose of  the article from the United States Environmental Protection Agency (EPA) is to discuss about the consequences that influence ecosystems in America. The researchers points out 6 of them: Life cycle event, range shifts, food web disruption, threshold effects, parasites and diseases and extinction. Their data comes mainly from other U.S. governmental organization reports, before President Trump’s election.   

 

Natural Ecosystem Change

English

In the article, “Natural Changes That Can Affect an Ecosystem”, Amy Harris discusses how an ecosystem can change naturally with the help of drivers, ecological succession, severe storms and other factors. For example, wind, rain, predators, and storms such as hurricanes are all examples of natural events that can change an ecosystem. An ecosystem can also be composed of non-living things such as, rocks, wind, air, soil etc. There are also different kinds of ecosystems for example, grasslands, tundra and many others.

A Disaster is a Disaster

The tundra

The article “Tundra” describe well the tundra lands and the impact of the climate change on these lands. It is a very interesting region as you can see on the images and on the video it is also really beautiful! In the Arctic tundra, the temperature is between 10 to 20 degrees Fahrenheit, and there is a lot of species that lives there like Artic foxes, gray wolves, caribou, polar bears, snow geese and musk-oxen! In the summer the sun shines 24 hours a day and it last 50 to 60 days.

Humans Hinder Animal Movement

English

The article I've chosen, "Humans Get in the Way of Mammal Movement" highlights the consequences related to human invasion of territories mostly occupied by animals. The text begins by noting how over fifty different land-based animal species suffer as a result of the modification humans have made to certain landscapes. The study conducted by the University of Maryland took into consideration a vast majority of species, across the entire globe. Ultimately the goal was to detect whether or not human interference with animal species effected the daily life of the animals.
