The manual method cost nearly VND700,000 ($33) per tonne, but the use of cutting machines, done the first time, cost just VND220,000 ($10) per tonne.

Just one month later, the immensely thick water hyacinth has blocked the flow of water and caused difficulties for waterway transport.

Maryland Falls Victim to Harmful Invasive Species - Invasive species are problematic because they can aggressively establish themselves very quickly after introduction, and often end up in direct competition with native species. Because of this, invasive species can quickly and dramatically alter natural habitats and displace native flora and fauna species. In the U.S. alone, 45 percent of species that are listed as rare, threatened or endangered are designated into this category in part due to invasive species.
