The Consequences of Ocean Acidification

The relentless rise in the percentage of atmospheric carbon dioxide since the Industrial Revolution is a well-known fact. Carbon dioxide is considered as one of the key players among the greenhouse gases that has contributed the most towards global warming, the current hot topic among environmentalists, scientists and even politicians. Another key issue is increasing being discussed nowadays is Ocean Acidification. Ocean acidification is an ongoing change in the chemistry of the ocean caused primarily by the ocean’s absorption of carbon dioxide from the atmosphere. What is Ocean Acidification Around 1/4th of the carbon dioxide released into the atmosphere via … Continue reading

The Menace of Marine Litter

Marine litter, long a neglected topic, has started to garner some attention. Marine litter is composed of a diverse mix of items from various sources and so a one-size fits all solution is unlikely to be effective. Abandoned, lost and discarded fishing gear (ALDFG), shipping wastes, plastic packaging (bottles, caps, bags, etc.) and plastic manufacturing pellets are amongst the most common and persistent items found. Comparing the feasibility and the financial case for recovery versus prevention for each of these groups reveals a worrying gap in our attempts to deal with the problem. Scale of the Problem Abandoned, lost and discarded fishing … Continue reading

The Problem of CO2-Caused Acidification

“The CO2 problem” has traditionally been understood as the fact that excessive CO2 produces global warming. But near the end of the 20th century, scientists started talking about a second CO2 problem, “ocean acidification”. Ocean acidification results from the fact that about 30 percent of our CO2 emissions have been absorbed by the ocean. This absorption keeps down the warming of the atmosphere that would otherwise be produced by these emissions. Ocean acidification involves the ocean’s pH, changes in which make the water become either more alkaline or more acidic. Tests have shown that “for more than 600,000 years the … Continue reading

A Message on Earth Day

Earth Day has now grown into a global environmental tradition making it the largest civic observance in the world and is widely celebrated event in which over one billion people from over 190 countries will participate by taking suitable actions for saving our mother Earth. The Earth Day was first organized in 1970 to promote respect for life on the planet and to encourage awareness on air, water and soil pollution. Each year a different theme or topic is selected. The theme of Earth Day 2018 is ‘End Plastic Pollution’. Plastic pollution is poisoning our oceans and lands, injuring marine life … Continue reading
