Mircroorganisms and Climate Change

 

Although it’s been clear that human activities have been and continue to be one of the biggest influences on climate and the environment, it is time that we give importance towards microorganisms, ‘the unseen majority,’ and how they too are being affected by climate change and human activities. It is clear that human activities have caused a loss in biodiversity, an extinction in plant and animal species and a loss of different communities and habitats. Nonetheless, microorganisms are not usually taken into consideration in the context of climate change, but their role is to maintain a healthy global ecosystem. Even though the effects of human impact are not visible on microorganisms, it is vital to recognize the importance of microbial processes in regards to creating an environmentally sustainable future.

 

Figure 1. The effects of human activities and agriculture on microorganisms. 



Microorganisms are involved in carbon sequestration, specifically marine phytoplankton, that fix a total net of CO2 similar to that of terrestrial plants. Therefore, it is critical to note such environmental changes as they influence marine microbial photosynthesis and fixed carbon storage in deep waters. Human activities that affect microorganisms include greenhouse gas emissions, pollution, agriculture, and population growth that will increase that of climate change, pollution, agricultural practice and disease spreading. However, microorganisms positively impact those factors by redeeming human-caused problems through improved agricultural outcomes, production of biofuels and remediation of pollution. Microorganisms not only influence the rate of climate change but can also take part our adaption tools and mitigation strategies.

    Its disappointing how everyone is seeing the effects of our innovations but they aren't reacting to the damage we are creating and what that implies for the future.

    I feel like the importance of microorganisms are vastly overlooked!! They are essential for our ecosystem, as tiny as they may appear.

How are health-care and trees related?

By: Ritzuko Gutierrez  Unfortunately, there are flaws in our system. One of these flaws is the lack of access to high-quality, affordable health care in rural areas. People who suffer from this issue, may be incentivized to rely on illegal activities. For example, illegal logging in order to get cash to pay health care needs. Tropical forests are mainly affected. The loss is greater than gain and it leads to a change in landscapes, livelihoods, biodiversity, and climate change. Providing high-quality health care to rural communities with limited resources and income options living nearly a tropical rainforest benefits both conservation and human health. Globally, 35% of protected areas are managed by local communities and when designing a conservation program, they are rarely considered in it. Although, this idea has benefits for humans and the environment, it also has its negative consequences. When applying, incentive-based conservation approaches, it can either go well or bad. B...

Oil Spills: 3D graphene

 By: Mary Aguilar          Oil spills has become a very big problem and causing a big problem for marine life.  This study discuss the importance of how oil spills have been a problem, and a solution on how to prevent oil spills from occurring. The article talks about how 3D graphene materials can remove dyes from the water. The 3D graphene can absorb both oils and organic solvents with also many other dyes have been studied in this research. The study concludes that there is possible use for 3D graphene but like many studies there is always disadvantages because it can clean oil spills under water but it is unable to absorb nanomaterials. Therefore the 3D graphene needs improvement in order to be able to solve the problem of oil spills, because if this is able to work then marine life can be saved.  Figure 1: Different ways graphene can be synthesized.  Riaz, M.A., McKay, G., & Saleem, J. (2017). 3D graphene-based nanostructure...

Is Hydroelectric Power actually a "Green" Energy Source?

Is Hydroelectric Power actually a "Green" Energy Source? Source: Tennessee Valley Authority (public domain) Greenhouse gases are gases that trap heat in the atmosphere, and the three major greenhouse gases are carbon dioxide, methane, and nitrous oxide. Natural sources of these gases consists of lakes, rivers, streams, and ponds as well. Lakes are environmentally beneficial because they are active, changing, and are important regulators of the three major greenhouse gases. That being said, lakes and reservoirs are known to be built for the purpose of generating power. So much so that water has been retained by dams that the global sea level rise has lowered approximately 0.02 inches per year in the span of 50 years. And since fossil fuels are not utilized to to produce hydroelectric power, lakes are known for their "green" energy sources alternative. Which is a common misconception because it is those lake and reservoirs that release powerful greenhouse gases into t...
