Number of Male loggerhead turtles are decreasing

Image
Over the past few years mostly all loggerhead sea turtle hatchlings have been female. Which can pose an issue for the growth and reproduction of loggerhead sea turtles, since the number of male sea turtles are diminishing. This issue can be directly linked to the Earth's rising temperatures.What determines the sex of a sea turtle is the condition or temperature of their nest. If the sand is hotter then the sex of the baby will most likely be female. Since, the Earth's global temperature has been rising over the years caused by greenhouse gases and other sources of air pollution, the sand has been getting hotter as a result. Even though there has been a majority of female baby sea turtles being born there is still enough adult loggerhead's out there to reproduce and keep the population sustained .Although, if this continues to happen they can struggle to grow their population in the future. It's very important to help so they won't be put in danger of dying out. N...

What Caused "Day Zero"?

Image
Everyone agrees that water is a necessity. In Maslow's hierarchy of needs, it is one of the first things that people need to survive in this world. What happens if all of a sudden, people have to cut down the amount of water they take in for both drinking and cleaning? The obvious answer is outrage, riots, and panic. That is what is currently happening in Cape Town. Because of a 3-year long drought, previously full reservoirs are running out of water to keep the cosmopolitan city running. The people are complaining. They pay taxes to live comfortably, but in return, they have to minimize their water intake to make sure everyone gets enough water for the day. There is a projection in mid-July called "Day Zero", or the day when most of the city's taps will be turned off to conserve water. What caused this tragedy to occur? Two words: climate change. According to National Geographic, about a decade ago, the city was warned that its current population growth and sh...

Lack of Animal Movement may Result in A Collapse in Biodiversity

Image
The last couple hundred Przewalski horses surviving off the Mongolian Grasslands. Humans take up around 70% of the earth's land surface area. This causes animals that roam freely throughout their habitat to move significantly less than they would in an unaltered landscape. An article in ScienceDaily says that mammals living in areas inhabited by humans move tow to three times less than those who live in areas untouched by man. When animals move they help important ecological processes such as transporting seeds and other nutrients throughout different areas which supports biodiversity. Additionally, mammalian movement reinforces the food chain by bringing different organisms to an area by way of hunting or being hunted. Thereof, if these animals are not moving as much as they should, biodiversity will plummet leading to the extinction of many plant and animal lives. In order to prevent this we have to make a conscious effort to stop taking more land and begin using the sp...
