Floodplains: The good and the bad

By: Maggilyn Cardenas 

    Floodplains provide ecosystem services that are important for humans. For example, drinkable water and provide fertile lands. However, floodplains also cause problems not only to humans but the environment as a whole. They can be responsible for soil, surface, and groundwater pollution. One of the bigger problems are wastewater treatment plants, landfills, and water handling facilities. Waste handling facilities help erosion and leaching behavior. Meaning that they can cause hazardous substances if flooded. The waste water treatment plants cause problems by releasing chemicals that were used in the plant. The primary goal for these is to protect the environment and are monitored by public environmental protection authorities. Another source mentioned in this article are contaminated sites. When they flood, they spread undesired chemical compounds in the environment. These are also under public environmental supervision. The European Community is presented to help these problems. They require an adequate and certain knowledge of pressure and natural hazards. The risks can only come down to three components: hazard, exposure, and vulnerability. The goal of this research is to identify the potential anthropic sources of pollution that are at risk of flooding that could possibly be induced to contamination of soil, surface water, and groundwater.

    This is a great tool to model potential risk. Would the environmentally sustainable focus be that urban planning could take into account where these potential pollution sources could be moved or built? Since environmental sustainability is about pollution prevention, that change in policy would reduce overall environmental and human health exposure during floods.

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...
