Now the he is a more experienced hiker, marine biologist Dr. Christian Heesch has developed a passion for taking on longer and more challenging trails than the ones he faced when he first started hiking. Longer hikes present a range of challenges that you won’t face on shorter trails, so try to keep all of the following in mind to ensure you stay as safe as possible.
Pack Light Fatigue is going to become much more of a concern as your hikes get longer, so you need to make the effort to counteract its effects and keep yourself as healthy as possible. In addition to taking along all of the food and water you will need for the hike, it is also a good idea to pack as light as possible so that you don’t get overburdened during your trek. Take A Windshirt You will need to take into account the possibility of weather conditions changing during the course of your hike, so it is vital that you pack kit to account for this. A good windshirt is light and will protect you from the elements when needed, making it a much better option that heavier jackets if you are wary about the effects of fatigue while on your hike. A Flashlight If you anticipate hiking for so long that it gets dark, you must take a flashlight along. Dr. Christian Heesch points out that a good flashlight, which should have new batteries and a fresh bulb, will allow you to stay on the trail and also make it easier to read maps or find other items in your kit. As a marine biologist, Dr. Christian Heesch is concerned about the effects that overfishing can have, both on the species that are intended to be caught and the many wild fish that get killed and discarded as a result of fishing. He has noted that many wild species have been experiencing population decline due to the effects of overfishing. With that in mind, all of the below are things that the average person can do in an effort to counter the effects of this issue.
Know What You Eat There is plenty of information out there that will let you know about the impact various types of fishing have on marine populations. By taking some time to research, you will be able to choose to eat fish from suppliers who make efforts to keep their practices as sustainable as possible, or those who catch fish in areas where they will not leave a large footprint in terms of population impact. Consider Farmed Fish In an effort to conserve a number of species, some suppliers have taken to farming fish specifically for consumption. This reduces the possibility that other wildlife will be caught up in nets to practically nil, plus it is a sustainable practice in much the same way as most other methods of farming. Spread The Word Dr. Christian Heesch is quick to speak to anybody who shows an interest in the impact of overfishing. By spreading the word and informing people of your concerns, you make it more likely that others will consider the issues that overfishing causes. Working as a marine biologist, Dr. Christian Heesch understands that there are few ecosystems more important than the coral reefs that embellish the oceans and seas. Much of his practical education in graduate school was spent on the study of coral reefs, giving him a level of unsurpassed knowledge. Over the years, he has learned many unique and engaging facts about the coral reef systems.
There are few underwater environments with more biodiversity than what is found in a coral reef. This is one of the biggest reasons that coral reefs are so important to the oceans as a marine resource. More than an exciting recreational excursion for divers, coral reefs provide a home for many aquatic organisms, they offer potential medicines for the human population, they offer a buffer for many shorelines, and they create the sands for our beaches. A coral reef is built from a collection of millions of coral polyps that closely resemble upside down jellyfish. In fact, corals themselves are a member of the cnidaria phylum along with anemones and jellyfish. To form a reef, this grouping of coral polyps leeches the extra carbon dioxide from the water and air atmospheres to create limestone. It is only the hard corals that create coral reef ecosystems. These types of corals have a rigid skeletal system that is comprised of calcium carbonate or aragonite. This structural build gives them the ability to create and support the reef. Soft corals, such as sea fans, do not have a rigid structure. There are no soft corals that can create a coral reef, yet soft corals may certainly live on a coral reef with thousands of other organisms and animals. Corals are unique in their own abilities and methods of reproductions. Scientists find it amazing that coral reefs have a completely symbiotic relationship with algae, where both provide a measure of support for each other. Coral is also one of the fewer organisms that can reproduce sexually and asexually via brooding or broadcast spawning. Coral reefs are found in shallow and deep waters, in cold or warm tropical climates. The coral reefs that grow in shallow waters or warmer environments are usually more prolific as the tepid temperatures are a better environment for growth. Corals that are in shallow waters are also more exposed to sunshine. One of the biggest concerns faced by marine biologists and all other scientists is the delicate nature of the coral reef. These structures are easily harmed, by natural environmental changes as well as human behavior. Dr. Christian Heesch works with his colleagues to promote a better education regarding the coral reefs that are endangered by climate change and pollution. |
