Some human activities have devastating consequences on the environment, while others have the sole purpose of improving or restoring the environment.
Unfortunately, the latter occasionally has negative results, despite having positive intentions. Humans negatively impact the environment in many ways: However, there are times when humans have good intentions, but our attempts to help the environment actually hurt it.
Here are 4 times human attempts to improve the environment back fired. Seem like a dumb idea already? Many sea creatures like mussels, barnacles, and tube worms need solid structure to attach to.
These organisms can help build the base of a food web to feed larger organisms like fish. Not to mention, many fish like having structure to hide in or around. The problem was the tires were tethered together and anchored to the bottom with steel clips attached to concrete blocks.
The clips corroded allowing the tires to break free, eventually smashing into natural reefs during storms. Some of the tires that were sunk off the coast of Fort Lauderdale, FL. But feeding wild animals is never a good idea, for several reasons. Ducks and geese fed white bread, crackers, popcorn, and the like have been linked to a wing defect called angel wing Figure 2 .
Feeding wild animals also reduces their natural fear of humans which can increase the likelihood of vehicle-animal collisions when the animals spend more time near humans trying to get food.
However, there are times when volunteers accidentally remove some natural materials that are important for the ecosystem. For example, removing leaf litter from stream bottoms or thorn bushes growing along a river bank is bad for the riverine ecosystem.
Bacteria decompose that leaf litter, insects eat those bacteria, and fish eat those insects. Likewise, the plants growing along a river bank filter out pollutants from reaching the water while providing shelter for other organisms like birds.
To be clear, picking up trash on the beach is a very good thing. However, removing natural materials from an ecosystem though unsightly is usually not.
Never leave the beach empty handed. US Navy USS Blue Ridge 4 Biocontrol agents gone wrong — When an invasive species starts wreaking havoc on an ecosystem because it has no natural predators to keep its population in check, it may seem like a good idea to introduce a predator to control it.
A famous example in ecological text books is the introduction of the cane toad into Australia. It was introduced to combat the cane beetle that was devastating the sugar cane crop.
This failed miserably as the toads were unable to eat many of the beetles. They did, however, thrive by feeding on other insect species and harmed potential predators of the toad with toxins they could emit from their skin.
Generally speaking, vertebrates are a bad choice for biological control agents because they usually do not specialize on a specific target species. Therefore, they will impact other aspects of the ecosystem.
Since this mistake almost years ago, scientists have recognized the risks of introducing biological control agents and now conduct rigorous testing before releasing any biocontrol agents into the wild .
The cane toad introduced to Australia. People who care about the environment and take action to help are incredibly valuable. Even within the categories presented above, there are many cases where ecosystem clean ups or biocontrol agents have been very successful.
The important idea here is to learn from our past mistakes to avoid repeating them. The trick is to remove our human biases as much as possible when determining what is good or bad for the natural world.
This is challenging to do, but it is essential that reality take precedence over human desires, opinions, or emotions.Yet while we still debate the merits of ‘nature versus nurture’ – DNA versus upbringing – years on, some experts now argue that our genetic inheritance has virtually nothing at all to.
Keywords: nature, nurture, human development, life span Introduction The term “nature” refers to an organism’s biological inheritance. The term “nurture” refers to an organism’s environmental experiences.
The interaction of nature and nurture, of genes and environment, influenced every aspect of mind and behavior to a degree. Neither factor operates alone.(Gottlieb, ; Mader, ; Rutter, ).  The interactions of genes with environment, called gene–environment interactions, are another component of the nature–nurture debate.
A classic example of gene–environment interaction is the ability of a diet low in the amino acid phenylalanine to partially suppress the genetic disease phenylketonuria. The nature vs nurture debate goes on and on, but still, it is a fact that we have traits that are predetermined by our genes, but we can still choose who we want to be as we travel through our lifetime.
Dec 12, · The model of nature/genes and nurture/environment is still used in behavioural genetics, as well as in popular culture, and has implications for public policy, including the treatment of offenders who claim that a genetic trait has influenced their criminal behaviour.
Humans negatively impact the environment in many ways: pollutants from industrial plants dumped into waterways, cutting down entire sections of forest, and prolific burning of fossil fuels resulting in global climate change are just a few examples.
