Paperback. Condition: Very Good. Toxic Algae is an epidemic threatening natural waterways locally, and globally. Harmful Algal Blooms (HAB) are an explosive growth of photosynthetic organisms in a body of water which can harm amphibians, fish, wildlife, pets, and human health by producing dangerous toxins. Fresh water systems such as ponds, lakes, rivers, and reservoirs are under assault from many directions increasing chemical imbalance stressing the aquatic water systems ability to stay in healthy balance. Toxic Algae in Harmful Algal Blooms (HAB) are an increasing threat to waterways throughout the country, and are reported with greater frequency in all 50 states. The water quality of our Ponds, Lakes, Rivers and Reservoirs are of prime importance to local communities, and the general health of local environments and ecosystems globally. Used for recreation, and as a food source for millions of people worldwide, healthy waterways are vital for ecosystems and people everywhere. Cyanobacteria are a photosynthetic bacteria which is normally a very productive part of the aquatic ecosystem. However, when Cyanobacteria break bad then very harmful toxins can be produced by some species which can be highly dangerous. Stressed from nutrient loading events such as a storm run-off, natural water bodies are being stressed to the point of imbalance introducing invasive species - including Toxic Algae. Cyanobacteria (called a Blue-Green Algae) are a type of photosynthetic bacteria. When a pond, lake, stream, river, or other water body experiences a nutrient loading event conditions can trigger an algal bloom which may result in a Harmful Algal Bloom (HAB). This book examines the causes of Harmful Algal Blooms (HAB) in fresh water systems, and explores methods used to combat the triggers of HAB. As climate change, population growth, and intensified agriculture and animal feeding operations grow the potential for increased frequency and toxicity of Harmful Algal Blooms (HAB) increases exponentially, and represents a real danger to water bodies, aquatic ecosystems, wildlife, livestock, pets and people everywhere. This book discusses how to treat and prevent Harmful Algal Blooms (HAB) providing a means of protecting your pond, lake, river, or reservoir from Toxic Algae.…

Paperback. Condition: Fair. Science isn't exactly Maeve's favorite subject, but she's still excited to be going to the Sally Ride Science Festival at MIT with her hunky tutor, Matt. Sure, the BSG and her annoyingly brilliant younger brother are going as well, but it's still almost kind of a date, isn't it? The festival gives the BSG a super idea -- an environmental science fair at Abigail Adams Junior High. But plans for a bubble gum factory nearby put Avery and Katani on opposite sides of an environmental issue -- and Avery finds herself in a bubble gum war with the Queens of Mean. …
